This is a
regularly scheduled stable release .
#2157: The new folder dialog now suggests a default path. Adjustable via advanced config defaultFolderPath.
#4272: The build script no longer sets -installsuffix by default.
#4286: Prevents a vulnerability that allows file overwrite via versioned symlinks
Note that the last issue is a security vulnerability. Symlinks on Windows are not supported and have not been created by Syncthing for a while. Nonetheless, if you use symlinks on Windows and Syncthing versioning you may have symlinks in your versioning directory from earlier versions. You must remove these manually. Syncthing can not remove them automatically because there are other things that look to us like symlinks but are not - deduplicated files, primarily. (This is one of the reasons symlinks are not supported on Windows.)
On other platforms the versioning directory is cleaned from symlinks as part of the upgrade.
